In this study, we evaluate the role of the NLRP3 inflammasome in ovarian aging and female fertility. Age-dependent increased expression of NLRP3 in the ovary was observed in WT mice during reproductive aging. High expression of NLRP3, caspase-1, and IL-1β was also observed in granulosa cells from patients with ovarian insufficiency. Ablation of NLRP3 improved the survival and pregnancy rates and increased anti-Müllerian hormone levels and autophagy rates in ovaries. Deficiency of NLRP3 also reduced serum FSH and estradiol levels. Consistent with these results, pharmacological inhibition of NLRP3 using a direct NLRP3 inhibitor, MCC950, improved fertility in female mice to levels comparable to those of Nlrp3−/− mice. These results suggest that the NLRP3 inflammasome is implicated in the age-dependent loss of female fertility and position this inflammasome as a potential new therapeutic target for the treatment of infertility. metadata Navarro-Pando, José Manuel; Alcocer-Gómez, Elísabet; Castejón-Vega, Beatriz; Navarro-Villarán, Elena; Condés-Hervás, Mónica; Mundi-Roldan, María; Muntané, Jordi; Pérez-Pulido, Antonio J.; Bullon, Pedro; Wang, Chun; Hoffman, Hal M.; Sanz, Alberto; Mbalaviele, Gabriel; Ryffel, Bernhard y Cordero, Mario D. mail jose.navarro@uneatlantico.es, SIN ESPECIFICAR, SIN ESPECIFICAR, SIN ESPECIFICAR, monica.condes@uneatlantico.es, maria.mundi@uneatlantico.es, SIN ESPECIFICAR, SIN ESPECIFICAR, SIN ESPECIFICAR, SIN ESPECIFICAR, SIN ESPECIFICAR, SIN ESPECIFICAR, SIN ESPECIFICAR, SIN ESPECIFICAR, mario.cordero@uneatlantico.es (2021) Inhibition of the NLRP3 inflammasome prevents ovarian aging.
